Device configured to selectively apply tools against a workpiece on a lathe

A device for selectively moving a first tool or a second tool relative to a workpiece on a lathe, the device including:

• a first and a second tool providing system, each of the first and the second tool providing systems comprising:
• a guide rail having a length direction;
• a slide slidably mounted on the guide rail, the slide being shiftable from a waiting position to a work position;
• a tool retainer on the slide;
• a block fixed relative to the guide rail;
• a first lever pivotably mounted to the block for pivotal movement about a first axis of rotation, the first lever having a first joint pivotably connecting the first lever to a linear actuator and a second joint pivotably connecting a second lever;
• the second lever having a first end pivotably mounted at the second joint to the first lever for pivotal movement about a second axis of rotation and a second end pivotably mounted to the tool retainer at a third joint for pivotable movement about a third axis of rotation;
• the linear actuator having a rod pivotably connected to the first lever, the rod extending in a direction not parallel to the length direction of the guide rail and being shiftable from a first position to a second position,
• wherein shifting the rod of the first tool providing system from the first position to the second position moves slide toward the workpiece and shifting the rod of the first tool providing system from the second position to the first position moves the slide away from the workpiece.
